Flashcards in Final Spring 2015 Deck (83):
1

medial lateral perterbations do what to hips

enact the hips, flexors unload
extensors load

2

2 gait adaptations

spin turn
step turn

3

without vision, pts have to really rely on

proprioception

4

stride length ___ with age

decreases

5

fnct of brain stem

primal- breathing, digestion

6

pariatal lobe

reach, grasping, reaction to env

7

temporal lobe

language, hearing, memory

8

power vs precision grip

power- like a baby or holding a hammer
precision - a needle or pen

9

thalmus

sorts data

10

feed forward

your reaction is due to a memory implant, it's anticipatory

11

catching a ball, your rxn happens

prox to distal

12

reaction time ___ with more practice

decreases as you learn

13

grasping is a ___ task

distal

14

explain ICF model

top tier- med condition
next 3 teirs - body impairment, activity limitation, participatio restriction
lower tiers - env, personal factors

15

Massed vs distributed

dist is best
Massed - for endurace pts
distributed- when they need more breaks

16

constant vs variable

constant - same always
variable - mix it up

ex: walking, always in a straight line on concrete vs zig zagging an doing steps

17

random vs blocked (order)

random is best for long term motor learning
blocked is good for beginner or cog issue

18

guidance vs discovery

guidence is less effective bc they just do what they are told

19

Fitts and Posners stages of motor dev

1- Cognition
2- Association
3 -Autonomy

20

Explain cognition stage of fitts and posner

experimentation, not sure what works best at this point, they are trying to find preffered strategies

21

Explain associative stage of fitts and posner

they are defining and mastering their preffered strategy

22

Explain autonomous stage of fitts and posner

its automatic, can now worry about env, and other factors

23

What is sx model theory

idea that movement is synergistic. there are 3 levels
novice - hardly any dof used
advanced
expert -release/use of all dof

24

4 main goals of Motor Learning

1. generalizability
2. retention-repeatable
3. quality of performance
4. resistance to change

25

4 stages of motor control

initial mobility
stablity
controlled mobility
skill

26

standing independently at what age

12 mos

27

Heirarchy dev with babies (what comes first and what after that)

attitudinal/postural reflexes
righting reactions
balace
posture mastery

28

Explain ATNR

where the head goes, the UE will follow

29

STNR

where head goes, arms follow and legs do opp

30

Tonic Labyrinthian

when head flexes trunk flexes
when head extends trunk extends

31

attitudinal/postural reflexes effect

tone of ENTIRE body

32

What sensory sx is most prominent in babies

visual

33

mental practice happens dt what part of brain

pre frontal

34

cognition includes what 3 things

attention
motivation
emotion

35

declarative memory comes from

explicit- hipppo

36

procedural learning happens due to what brain part

cerebellum

37

3 requisites of locomotion

stability
progression
adaptability

38

___controls reach, while ___ controls grasp

prox-reach
distal-grasp

39

voluntary control is due to

frontal lobe

40

coordinator of mvmt

cerebellum

41

Fitts law

accuracy and speed, large vs wide target) (bigger target the faster you can complete the task-not as fine and skilled) (start with bigger target first)

42

voluntary control happens due to

frontal lobe

43

sensations needed for posture and fine motor control

all (sight, touch, proprioception, vestibular)

44

ATNR is beginning of

eye hand coordination

45

3 things needed for reflex theory

receptor
pathway
effector

46

motor control and motor memory dt

cerebellum

47

language hearing and memory

temporal lobe

48

executive brain fnct

frontal lobe

49

sight dt

occipital lobe

50

sensations dt

pariatal lobe

51

grasp reflex integration occurs

6mos

52

intrinsic vs extrinsic feedback

intrinsic- within
extrinsic- outside body

53

5 main parts to gait measurment

step length
step width
stride length
velocity

what is step length

1 foot strike to anotehr

55

what is stride legth

q 2 steps

56

what is step witdth
